Case Type   : 系统内部使用工具
Case Name   : 在主节点执行failover是否成功
Create At   : 2021/01/20
Owner       : opentestcase015
Description :
    1.在主机上执行failover（主机执行，不stop备机）
    2.执行refrashconf进行信息写入
    3.重启集群
    4.检查主备状态是否正常
    5.环境恢复
Expect      :
    1.在主机上执行failover成功
    2.执行refrashconf进行信息写入成功
    3.重启集群成功
    4.检查主备状态，主备状态正常,主备切换失败
    5.成功
